To all w Ito/m, t may concern:

^ Beit known that L'Ennns'r PALLADiNI, a citizen of the United States, residing'at Albuquerque, in the county of Bernalillo, State of New Mexico, have invented 4certain new and useful Improvements in Locks;`and

I do hereby declare the following to rbe "a full, clear,',and exact description of the invention, such as will `enable others` skilled in the art to whichit appertainsto make and use the same.

This invention relates to locks andl partic'ularlyr topermutation locks.

` The object of the invention 'resides in the provision of alock of the `character named which embodies ar novel construction designed to render it impossible yto open the lock unless the combination and method of operating same is known, the lock being further designedwand constructed to permit of the combination being changed .when desired. "l

A further object of the invention resides in the provision of a lock` ofthe character named'constructed and arranged to have a wide field of application, and capable of being operated inthe dark without the use of a key. s, l i

With the above and otherobjects in view the invention consists in the details v of construction and in the arrangement and combination of parts to be 'hereinafter more fully described and particularly pointed 'out in the appended claim. ,v s

Fig. r lele is a front elevation of a door and the `frame therefor showing the invention applied thereto.

4Refe'rrfing"to the drawings A indicates a door frame ,of the usual hollow construction and B a door hingedly mounted in said frame. The frame 'A includes an outer member 15, andan inner member 16 disposed opposite each other as is usual in the construction Yof door frames. The outer member `is provided with spaced openings 17 through which are adapted to proliect respectively apertured keepers y18 carried b vfthe ,door B when said door is disposed inclosed position. YThe outer member 15 isfurther .provided with an opening 19 4through which is adapted toproject a keeper 2O carried b v the door B when said door is in closed position, it being noted that the keeper "20 is provided with an opening 21 for a purpose that will presently appear. Securedto the inner side of the member 15 isa frame C in which is mounted certain mechanisms' to be `hereinafter referred to. The `member 15 is provided on its inner side with a longitudinal groove 92 which intersects the openings K17. Slidablv retained in the groove 9,2 are locking bolts 23 and 24. Secured to the bolts Q3 .and 24 respectively are'rack bars 25 and 26. Connected to the rack bar 25 one end of a spring 27, while the other end of said spring isconnectedto the frameC. This spring 27 constantly tends to hold the bolt 23 projected across one ofthe openings 17 and through one ofthe keepers 18'when said keeper is disposed in y the 'opening 17. Another spring 28 has one secured to the rack bar 26 and its other` end to the frame@ and constantly tends to' hold lthe-'bolt 24 projectedacrossfthe other opening 17 and through the other keepery 18 when said keeper isdisposedin the opening 17. Mounted upon the member 16 in proX- imity to the rack bar 25 is a U-shaped bracket 29 between the arms of which is rotatablyjmounted a ratchet wheel :30.v .,Se-

, frame C is a plate 32.l Rising from'vthe plate 32 adjacent the ratchet wheel 3() is a forked bracket 33 between the arms-of which is pivoted a locking pawl y34 which coperates with the teeth of the ratchet wheel l30,` said pawl being normally heldin engagement with the ratchet wheel 30, by means of a spring one end of which is secured to said pawl and the other end .to a plate 36 carried by the bracket 29.v Rising from the plate 32 at substantially the center of. said plate is a bracket37 to which is pivoted a lever 38. One end of this lever 38 eX- tends between the arms of thebracket 33 and has-'pivoted thereon anoperatingpawl 39 'normally held in engagement with the ratchetwheel 30 by means-of aspring 40 one endof which is secured to the pawl 39 and its other end to theplate 36. The end of the lever 38 remotevfrom the ratchet wheel 30 is normally held elevated by means of a spring l'41 interposed between same and the plate 32'. Mounted upon the plate 32 betweenl the bracket 37 and spring 41 is a. bracket42 upon which ispivoted a leverl 43 for movement in a plane transverse the lever 38 and engaging the sidevof the' lever 38 remote from the plate 32.4 Slidably. mounted in the member15 isa plunger 44 the end of which that'is disposedwithin the frame A being pivotally connected to the free end of the lever43. Bythisconstruction it will be obvious that when the locking bolt 23isprojected through its, coperating -keeperQ18 intermittent depression of the plunger 44 will rotate the ratchet wheel30 so as .towithdrawA theAV locking Abolt 23 from its .coperating keeper 18. The number of depressions of the plunger 44.*necessary to effectthe retractionoftherbolt23 -is dependent upon ,the position of the yrack bar A25 with respect to the ratchet wheel 30 when the rotation of the ratchet wheel 30.is instituted by the depression of the plunger 44. .'Ihe rack bar 26 and bolt 24 lare `operated by armechanism similar in everyrespect vtorthe mechanism which operates the :rack bar 25' and bolt 23 and for this reason detail reference to the operating mechanism [ofi the. rack bar 26 and bolt-v 24 will be omitted, it being noted that the reference characters employed in describing the mechanismfor operating-the rack bar 25 and the bolt 23 will. be applied to similar parts ofv the1nec hanismfor operating the rack bar 26 and bolt 24.

...'LRotatably mounted in the frame C is a shaft 45 upon which is fixed a disk 46 havinga recess 47 in the periphery thereof. Pivotally connected to the disk 46 at diamet'rically "opposite points are arms 48 and 49. The arm 48 is connected to the ypawl 34 andthe pawl 39 of the mechanism y,which operates the bolt 23 by means of links 50 and 51 respectively, while the arm 49 is connected to the pawl 34 and the pawl 39 of the mechanism which operates the bolt 24 by means of links 52-and 53 respectively. Slidably mounted in the frame C is a bar 54,y said bar being'adapted to move transversely of the bolts 23 and 24 and` carrying a finger 55 `engaged in the recess 47 vwhereby the reciprocation of said bar will oscillate the disk 46 as will be obvious. The bar 54 hasV one end reduced las'at 56 so as to formshoulders 57. Encircling the reduced portion 56 and bearing against thel vframe yC and the shoulders 57 is a spring 58 which constantly tends to hold the bar 54 at the limit of its movementin one direction. Rotatably mounted in theframe C and extending through the member 15 is an operating vshaft 459 having a collar 60 fixed thereon provided withsub-l stantially Yopposite wings 61 and 62. The end of thecollar 60 adjacent the member 15 isl provided with a lug 63 adapted to detachably engage in a recess 64 formed in a bearing 65 on the frame C and in which bearing the shaft 59 rotates. The shaft 59 is capable of limited longitudinal movement and is encircled by a spring 66 which constantly urges the shaft and the collar 60L in the direction of the bearing 65. yThe shaft 59 has fixed on the end thereof remotefrom the frame C van operating handle 67 whereby same may be conveniently rotated or moved longitudi-l nallyagainst the influence of thespring 66 as (desired. The bar 54 has the end thereof adjacent the shaft 59 recessed to form a shoulder 68 against which the wing 61 is adapted ,to engage when the shaft 59 is rotatediin one `direction and whereby the bar 54 is moved longitudinally and the disk 46 rotated. When the bar 54 'is' moved longitudinally againstthe induence ofthe spring 58 by the rotation of thev shaft 59 therotation ofthe disk 46 will draw the pawls 34 i 'provided with a recess 7 0 forming la. bill 71 adapted to be normally disposed across the opening 19. The latch (39 is normally held in position to dispose the bill 71 across the opening 19 by means of a spring 72. The end of the latch G9 adjacent the shaft 59 is recessed to form a shoulder 78 against which the wing 62 is adapted to engage When the shaft 59 is rotated in one direction, such rotation of the shaft 59 serving to move the latch (39 against the influence of the spring 72 and the bill 71 ont of the limits of the opening 19. rlhe edge of the latch G9 adjacent the disk 46 is recessed as at 74 and yieldingly mounted'in the frame C is a block 7 5 provided with a groove 7e in which the latch 69 slides. The block 7 5 is constantly held in engagement with the edge of the latch 69 adjacent the disk 46 by means of a spring 7T. W hen the latch (39 is moved so as to shift the bill 71 out of he limits of the opening 19 thc block 75 will automatically pass into the recess 74 and lock the lat-ch against movement under the influence of the spring The keeper :20 in addition to beingr provided with an opening 'LZ1 to receive the bill 71 has a forked :tree end forming arn1s'78 and 79, When the latch (S9 is locked retractedby the block 75 and the keeper is moved into the opening 19 by swinging the door B it will he obvious that the arms 7 and 79 will be disposed on opposite sides of the latch 69 and engage the block 75 so that the movement of said keeper will in turn move the block '75 against the inlluence of the spring 7T. When the open ing 21 alines with the bill 71 the block 75 shall have lleen forced entirely out of the recess 74 and the spring 72 will then operate to move the latch G9 longitudinally and engage the bill "llthrough the opening 21. Mounted in the frame C are cylinders 8() and 81 and arranged in these cylinders and operating through the member 15 are spring plungers and 83 respectively Which normally project a slight distance beyond the outer side of the member 15 and are forced inwardly by the closing of the door B. Through the medium of these plungers an initial opening movement is imparted to the door B when same is released.

Assuming they door B to be locked in order to effect the opening thereof it is first necessary to move the shaft 59 longitudi- Copes of this patent may be obtained for ve cents each, by addressing the Commissioner of Patente i nally against the influence of the spring 66 so as to disengage the lug 63 from the recess 54 and the Wing 61 from engagement with the shoulder 68. The spring 58 will then move the bar 54 toward the shaft 59 and rotate the disk 46 with the result that the paivls 84 and 89 will be moved into engagement with the respective ratchet Wheels 80. The plungers 34 are then operated to retract the bolts 23 and 24 from the keepers 18. The shaft 59 is then rotated to move the latch G9 and disengage the hill 71 from the opening Q1 when the plungers 82 and 83 Will operate to impart an initial opening movement to the door B. When the door B is closed the latch G9 will loe operated to engage the bill 71 through the opening 21 previously described. The shaft 59 is then rotated to engage the iving 61 against the shoulder 68 and thus movevthe bar 54 against the influence of the spring 58. This movement of the bar 54 will rotate the disk 4G to Withdrawv the pawls 34 and'89 from engagement with respective ratchet Wheels 80. The springs 27 and 28 will then ant0- matically operate to project the bolts 23 and Q4 through the keepers 18 as will be obviens;

lhat is claimed is y A lock comprising a casing, a locking bolt slioably mounted therein, spring means constantly tending to hold said bolt in projectedor locking position, a ratchet Wheel mounted in the casing, a lever pivoted in the casing7 a paivl pivoted to said lever and coperating with said ratchet Wheel, means for rocking the lever to rotate the ratchet Wheel, a locking pavl pivoted in the casing and coperating With the ratchet Wheel, means for disconnecting bot-h of said pavvls from the ratchet Wheel when the bolt is in projected position, means for rocking the lever to ,rotate the ratchet Wheel`r and connections between the ratchet Wheel and the bolt whereby the rotation of said Wheel under the influence of the rocking of said lever Will retract the bolt.
